AUTOMATIC FILLING-REPLENISI-IING LOOM.

To all whom it may concern Be it known that I, FREDERICK T. AR'rz, a citizen of the United States, residin at Manchester, county of Hillsborough, tate ofNew Hampshire, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in,

automatic filling replenishing looms, and the principal object thereof is to provide a simplified form of feeler mechanism which may be applied to the usual form of Northrop loom to adapt the same for use with fillingcarriers having feeling recesses or slots to receive the end of the feeler when the filling on the carrier is nearly exhausted.

Another object of the invention is to provide a simple but effective means of removing the feeler from feeling position upon the stoppage of the loom and for withholding. the same from operativeposition until' the loom is again started under power, thereby permitting the loom to be turned over by hand and the shuttle boxed without danger of improperly initiating the action of the transferring mechanism during such manual operations as may be necessary or desirable during the stoppage of the loom.

Other objects of the invention and the nature thereof will more fully appear from the following description and the accompanying drawings and will be particularly pointed out in the annexed claims.

The drawings illustrate the invention as applied to the well known Northrop type of loom, suflicient portions of the loom being illustrated to show the relative positions of the parts of the loom and the novel mechanism applied thereto.

In the drawings,

Figure 1 is a plan view, broken away in the middle, of a portion of a Northrop loom with the present invention incorporated therein;

Fi 2 is a view of a portion of the loom showlng the improved feeler and the mecha nism operated thereby to initiate the action of the transfer mechanism;

Fig. 4: is a detail view of a portion of the same showing the latch in a different position; a

Fig. 5 is an end elevation of the counterweighted feeler mechanism.

Fig. 6 is a detail View of a means which is actuated preferably by the knock-off lever to withdraw and withhold the-feeler from pperative position during the stoppage of the In the usual types of automatic filling replenishing looms the bobbins or other filling carriers are provided with a bunch which is wound upon the barrel of the filling carrier a short distance from the base thereof before the main or service winding is laid.

predetermined portion of the bunch is wound off, other mechanisms are engaged which cause the operation of the transfer mechanism to remove the nearly exhausted filling carrier from the shuttle and substitute a fresh carrier therefor.

In such cases the discharged filling carrier retains more or less of the bunch which must be stripped off before the filling carrier is re-wound. This entails considerable'loss of time as well as a substantial loss of material. In order to overcome these. losses and also to avoid the necessity of such exact adjustments as are required in feelers operated by bunches on the filling carrier, filling carriers have been devised in which the barrels are slotted or recessed to receive the end ofthe feeler, when the filling is sufficiently unwound to expose the slot.

The slotted or recessed filling carriers may be so wound that when the feeler slot is exposed just enough filling will remain on the carrier to complete a pick from the feeler end of the loom to the battery end, leaving. the filling carrier clean when discharged and thus avoiding. the necessity of stripping the. bobbin and the wastage of filling; Furthermore. such feelers may have a greater amplitude of movement when sub- 1 91 of impr per tran f g y 28 of the transmitter which not having been raised lies within said slot.

In making adjustments and repairs to the loom, and often in splicing the warp, it is desirable that the feeler be withheld from feeling position during the stoppage ofthe loom, to prevent improper transfer or injury to the shuttle or feeler when the loom is turned over manually, and this invention includes means for withdrawing and withholding the feeler from operative position so long as the shipper is out of running position.

In the preferred embodiment of the invention illustrated herein the shipper 45 is shown in running position, held in the offset I portion of the slot 46, the shipper being engaged by one end of the usual knock-off le ver 47. The feeler withdrawing mechanism may conveniently be in the formof a block 48 slidably mounted in a groove v49 in a lateral extension 50 of the bracket 29 and connected by an arm or rod 51 to the knock off lever 47 preferably by a slot and bolt connection 52 to permit sufficient relative movement to compensate for the arcuate movement of the knock-01f lever.

The end of the block 48 is preferably pro vided with a beveled portion 53 (see Fig. 6) which underlies the transmitter 28 near its pivot, and provides an inclined surface or wedge adapted to raise one end of the transmitter lever when the knock off is actuated to release the shipper from running posi tion.

During the normal operation of the loom the shipper is retained in the position illustrated in Fig. 1 and the block 48 is out of engagement with the transmitter. When however the loom is stopped manually or by a usual automatic stop mechanism common to looms of this type the knock off lever is moved about its pivot thrusting the block 48 beneath the inner portion of the transmitter thus raising its end 28 and thereby elevating the latch 38 out of the path of the vibrating actuator 41 so that transfer cannot be called for during the stoppage of the loom or while the loom is operated manually.

At the same time the opposite or outer end of the transmitter is depressed, forcing the link 26 and the arm 25 of the bell crank lever downward thereby rocking the other bell crank arm 23 forward and withdrawing the feeler from feeling position.

The block 48 preferably is retained in its position under the transmitter during the stoppage of the loom and until the knock ofl lever is restored to the position in which it is illustrated in Fig. 1 by the placing of the shipper in running position.

While the mechanisms herein disclosed comprise a preferred embodiment of the invention particularly adapted to the Northrop type of loom it is to be understood anism upon restoration of the thatthe same is merely illustrative of my invention and that the same may be embodied in different forms'of mechanism and may be applied to various other types of looms within the scope of the following claims.

Having fully described my invention, what I claim asnew and desire to secure by Letters Patent is:

1. In an automatic filling replenishing loom comprising feeler mechanism and stop mechanism including a shipper and a knockoff lever therefor, means connected to the knock-off lever adapted to render the feeler mechanism inoperative during the stoppage of the loom and to release said feeling mechshipper to running position.

2. In an automatic filling replenishing loom comprising feeler mechanism and stop mechanism including a shipper and a knock off lever therefor, means connected to said knock-off lever adapted-to removethc feeler from feeling position upon the actuation of the knock-off lever to withhold the feeler from operative position during the stoppage of the loom and to release said feeler upon restoration of the shipper to running position.

3. In an automatic filling replenishing loom having a shuttle equipped with a filling carrier having a feeler recess in the barrel thereof, transferring mechanism, a controller shaft therefor having a latch normally positioned in the path of a vibrating actuator, a feeler, a bell crank lever having one arm connected to said feeler, a central pivoted transmitter connected at one end to the other arm of said bell crank lever and having its opposite end underlying said latch whereby the feeler upon entering the feeling recess in the filling carrier upon substantial exhaustion of filling will permit said latch to lie in the path of the vibrating actuator and be caused thereby to initiate the action of the transfer mechanism.
